Michelle, a devout Catholic, struggles with her lustful thoughts about her stepbrother's cock. She prays for forgiveness, but her body betrays her, aching for that forbidden thickness. One evening, she finds him sleeping naked, his cock semi-hard. Unable to resist, she gently strokes it, feeling it grow in her hand. She tentatively licks the head, tasting his pre-cum, before hungrily taking it into her mouth, her pussy dripping with wetness. She rides him, impaling herself on his cock, as they both give in to their taboo desires, fucking wildly until they collapse in a sweaty, satisfied heap.
